Did you know time speeds up the further away you are from gravity, which means that what people think are billions of years old are infact only thousands.
If we go looking for it, we may not even recognise it. I image that in great irony, we would stumble across a species on their way to world domination but since we do not find cities and artificial satellites, we would move on.

Intelligence seems very difficult for evolution to develop and it seems a very very precise series of circumstances is required to pressure and organism into sentience.
You're basing your assessment on the history of Earth and it's creatures. One planet from one solar system out of billions. Have you stopped to wonder that perhaps the conditions we arose in aren't as conducive to intelligence/sentience than other parts of the universe?
We live in our own bubble and our intelligence appears to be marred by that. I highly doubt that we took the only road available in this universe to sentience.
An amino acid has been found on a comet for the first time, a new analysis of samples from NASA's Stardust mission reveals. The discovery confirms that some of the building blocks of life were delivered to the early Earth from space.
Amino acids are crucial to life because they form the basis of proteins, the molecules that run cells. The acids form when organic, carbon-containing compounds and water are zapped with a source of energy, such as photons – a process that can take place on Earth or in space.
